*short reverie of the Doctor as part of the cast of Time Bandits* /reverie

The problem there, as I see it, is, we've only seen one crack large enough for a corporeal being to get through, and that didn't seem to end to well for the weeping angels concerned. Prisoner Zero was not limited by a phyical body when he came through the crack. The doctor's arm has been through a crack, but it very quickly started pouring out the light that ater Rory, so I suppose I am saying that we have no evidence that it would be safe for the doctor to travel through them at this point. Also the navigation issue of going from one point to another without the Creator's map would seem almost insurmountable...
